device has reduced materially: the original cost of the articles and its maintenance."-

5. The edges of the guard. at thetop and bottom are-provided with diagonal slots 14 adapted: to receive bolts 15::havingnthu1nb nuts 16 by means of which the guards can be;

securely clamped-31in place on the 1: valves. One ofthe sections of the guard isalsoupror- V-vidediwith ears 17 havingnotches 18 therein to": receive a bolt corresponding: ;,to .;those at the top and bottom of the guardandhaving a si1nila'r means for tightening the bolt and locking the telescoping; ends of the. guard sections securelyto gethera The edges ofthe plates composing the guardextend to a-point between'the boiler front and the water glass on teach side and} positively prevent-- the" engineenand firemanfrom. being injured by the"flying glass orrscalded bythe water in case of breakage of the water glass. When and clamping them on said valves, said walls having: other openlngs therei11,"and glass I loosened and the guard opened or spread sufliciently to disengage the wings from the water glass and the valve.

In Figs. l and 5 I have shown amodnied construction, which consists in provlding plates 19 and 20 an'd19 and 20, arranged inpairs withhinges 2l'at their abutting" the plates 19 and 20, whose hin'ge,being on the,.,out side, may extend -the length of these plates. ,lPanelvopenings 22 are provided. in

the plates, in which the glass sections 14c, are inserted in substantially the same way as described with reference to the previous.

2. The combination, with a water glass Hand valves therefor, .7 of a guard lnterposed between said valves, said guard'being; V- shaped,substantially,'in cross section, having its apex at: the front and open at the rear and adapted at the top and bottom to seat on said valves, the rear portions of the walls of said guard having openings therei in, rods extending transversely at the rear of said guard and fitting within said openings for drawing the walls of said guard together plates fitting within sald last named openingswand through which plates the water glass is visible. i
